CHISEL HOLDER.

Application led May 6.

T0 all whom t may concern:

Be it known that 1, Jol-IN J. 'MAoEiQ J r., a citizen of the UnitedStates, residing at Cliadron, in the county of Dawes and State ofNebraska, have invented certain new and useful Improvements in ChiselHolders, of which thefollowing is a speciication.

The present invention relates to a device for holding a chisel, and'hasfor its principal object to provide a structure which is efficient inholding a chisel for severing the nuts on bolts which hold theangle-bars or lish-plates to the rail. Ordinarily, a man is employed tohold the chisel, while the sledge is being used, and this man is inconsiderable danger for various obvious reasons. The present holdereliminates this man and holds the chisel in proper position for engagingthe nut or square'end of the bolt. v

Another vimportant object of the invention'is to provide a holder ofthis nature, which is adjustable so that it may be easily engaged withthe rail.

A further object of the invention is to provide a device of this naturewhich is simple in its construction, strong, durable, reliable, easy tomanipulate, and well adapted to the purpose for which it is designed.

With the above and numerous other objects in view, as will appear as'the description proceeds, the invention resides in certain novelfeatures of construction, and in the combination and arrangement ofparts, as willy be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a side elevation of the device, embodying the features of myinvention;

Fig. 2 is a top plan View thereof;

Fig. 3 is a transverse section therethrough, taken substantially on theline 3-3 of Fig. 2, looking in the direction of the arrows;

Fig. 4 is a fragmentary elevation, showing particularly the nut-engagingmember; and

Fig. 5 is a sectional view through the clamp, showing the handle of thechisel mounted therein.

Referring to the drawing in detail, it will be seen that 1 designates aplate which is adapted to rest on top of the rail and extendlongitudinally therewith. A pair of spaced parallel standards 2 risefrom the 1925. Serial No. 28,342.

plate 1. A bolt or pin 3 extends transversely across vthe upper ends lofthe standards 2. A plate thas one endlrolle'd, as at 5, so as torotatably engage the bolt 3. The other end' of this plate ll is curvedarcuately as at 6 to form a clamp section.

Another clamp section 7, of arcuate for-' mation, is pivoted as at 8 tothe fclamp section 6, and has an extensionr) for receivmg a bolt 10piercing' the plate 4. The

nut 11 is engaged with the bolt, for engaging the sections 6 and'7 12 ofthe chisel 13.l

A pair of standards lat rise from the baseplate 1 andare spacedlongitudinallythere- Vabout the handle of and receive betweenthe upperends thereunder edge of the ear 21 being provided` with a notch 2st. Anarm 25 is pivotally engaged by means of a sleeve A26 to the pin 23, andthe extremity thereof is provided with a recess 27. The upper edge ofthe sleeve 26 is provided with a lug 28. 'A spring 29 is coiled aboutthe pin 23, between the ear 22 and the sleeve 25, and one end thereofengages the portion 20, while the other end thereof engages the arm 25as at 30, and normally holds the arm in the positions shown in Figs. 2and Il. This arm, however, may be swung to a position at right angles tothat shown in Figs. 2 and 4, at which time the lug 28 will engage' inthe notch 24', and thus hold the spring 29 under tension. The nut to besevered is to rest in the recess 27, as is shown to advantage in Fig. 1and will thus be prevented from turning. rlhe member 16 includes ahorizontal portion 32 and a vertical portion 38. The horizontal portion32 is corrugated on its lower surface for cooperating with thecorrugating upper surface of the portion 18. The horizontal portion 32is also provided with a pair of slots 34 which are adapted to be placedin registry with slots 19, so that screws 35 and 36 may be passedtherethrough and engaged in the plate 1, and thus the portions 18 and 32may be held in adjusted positions in relation to the plate on the plate1.`

l, for the purpose oi varying the dist-ance between the portions 2O and33. The portion 33 is provided with a longitudinally extending slot 37.A bowed member 38 is pivoted .in the lower end of the slot 87 as at 40,and is provided with an extension lll, which is disposed under thehandle har l5, so that the bowed portion may be swung out of the slot 37and out of engagement with the fish plate. A spring 4t2 is engaged atone end with the screw 36 and at the other end with the upper portion oithe bowed member 38 and normally holds this bowed member in the positionshown in Fig. 3.

A pairgof members L14 and are provided at-the other end of the plate land are similar in construction to members 16 and 17, except that memberf5 is not provided with the ears 2l and 22 and associated parts, and thebowed member' oi2 the member ll5 is not provided with the extension 4l.Furthermore, members and 45 are not quite as large as members 17 and 1Grespectively. These members 16, l?, eel and l5 are adapted to engage thefish-plates or 'the sides of the tread of the rail, so asto hold thebase-plate I in position on the rail, so that the chisel may be 4engagedwith the nut disposed in the recess 27 of the arm `When thus disposed,it will be seen that the Sledge may be struck against the chisel -forsevering the nut from the bolt as is usual. This will eliminate thenecessity or" having a separate man for holding the chisel and willeliminate the dangers incident to such a man holding the chisel.

1t is thought that the construction, oper- Having thus described myinvention, T

what I claim as new is:

ln a structure of the class described, a plate, a pair of adjustablemembers mounted on the plate and having depending portions, one of saiddepending portions being slotted vertically, a bowed member hingedlymounted in the slot, a spring for normally holding the bowed memberextended in- Vwardly of the slot, the other depending portion providedwith a pair of apertured ears,

a pin extending through the apertured ears, an arm slidably androtatably mounted on the pin and provided with a recess for engaging thenut, and a spring on the pin forengaging the arm to hold it in a raisedposition for engaging the under side of ythe nut, and clamping meanspivotally engaged with the plate for holding a chisel in engagement withthe nut supported in the arm.
